Application filed. lllarch 2?, 1914. Serial No. 827,610.

To all whom it may concern:

B'e it known that I, Wnsnnr A. PAUL, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Lever Mechanism, of which the following is ea specification, reference being had therein to the accompanying drawing.

My invention relates to a lever mechanism illustrated as applied to a plow of a type employed as one of a gang attached to a common support. r j

The object of my invention isito provide a simple and effective means of limiting by adjustment the play of a lever, so that the movement of the object affected thereby is definitely fixed. j r y j Referring to the drawings in which similar numeralsindicate identical parts; Figure 1 is a side elevation of a plow showing my improvement. Fig. 2 is a detail section on the line m -w of Fig.1 and llig. ,3 is a detail section on the line ya; of Fig.1. Fig. 4 is a detailview of one of the parts.

The plow-beam 1 is'pivotally supported on the rear of a frame 2, COIii II IQ II tO plows of this description, and carries upon its rear end a plow body. 3. A gage wheel 4 is sup ported on a wheel bail 5 pivotally mounted on a casting 6 secured to the beam 1, An upwardly and forwardly extendingleyer5 is also pivotally supported on; the casting 6 on the same pivot as the wheel bail 5 and is connected to the latterby a brace 7. is Aquadrant 8 is secured to the beam 1 in an upright position and rigidly supported by braces 9 and 10 bolted to the casting 6 and extending to the upper end of the quadrant to which they are secured by a-suitable bolt.

A member 11 is movably supported on the quadrant 8; the upper end ofthe member 11 is formed at a right angle to the main portion and has thereon a slot 13 throu h which the quadrant 8 projects The end 2 is elongated and hasa chamber 14 in which is a coil spring 15 bearing against thennder side of the quadrant 8 and a. cotter in the bottom of the chamber 14. Theiquadrant 8 is provided with notches 16with any one of which the portion 12 of thememberll over the slot 13 is adapted toengage; the portion 12 forming a tooth preferablyintegral with theend .12 Upon the leyer 5 is secured a bracket 17 having an upper pertion18 extending outwardly with an opening therein in which a lifting latch 19 is movable. A coil spring 20 encircles the lifting latch 19 betweenga shoulder 21 thereon and the portion 18. The lower end of the lifting latch 19is a hook 21 adapted to engage with a lug 22 on the member 11; a latch rod 23 is hooked to the upper end of the lifting latch 19 and extends along the lever 5 fto a connection with a rocking grip 24 pivoted on the upper end of said lever. On the op posite side of the lever 5 is a latch. 25 havingits upper end projecting through an eye 26, forming part of a bolt utilized to secure the bracket 17 to the lever 5, and a rod 27 is connected to the latch 25 and to a rocking grip 28 on the upper end of the lever 5 Between the eye 26 and a pin 29 on the latch 25 isa coiled spring 30. The lower portion 31 of the latch 25 is bent at a right angle and projects through a slot 32 in the lever 5 and similar slots in the bracket 17 and lifting latch 19, and is secured against displacement by a washer 33 on the end thereof, held in position by a pin or cotter, and a washer 34 retained thereon in a similar manner against the lever 5. The port-ion 31is adapted to engage with the notches of the quadrant and with a notch '35 in the member 11, the latter being movable along the quadrant 8 on a pin 36 attached to the quadrant 8 and projecting through a slot 37 in the. member 11 concentric with the quad ra ts a arm ,38 is secured to the lever.5 and has connected thereto a coil spring 39 which extends forwardly to engagement withathe hook end of a rod 40, the forward end. of

said rod extending through an opening in a bracket 41 secured. onthe quadrant 8 and threadedto engage with a hand nut 42 by the turning of which the tension .of the spring 39 can be increased or diminished.

In the operation of my device it is to be supposed that the position of the parts shown isto regulate the depth of plowing determined, it is often; necessary however to raise the plow from the soil to avoid an obstacle or, forpurposes of transportation and it is desirable that when. lowered into operation the plow should again penetrate the soil :to the samedepth as before, the up- -ward movement of the gage wheel being predetermined and limited for the required depth of plowing. It will be seen that by operating the grip 28 the latch will be raised from engagement with the notches in the quadrant 8 and the notch 35 'of'the member '11; consequently a'downward movement of the lever 5*, assisted bythe tension of the spring 39, will force the gage wheel 4 downlever 5 is moved upward. the movement, of

the lever continuing until the portion 31 reaches the notch 35 in the member 11' and the opposite notch on the quadrant 8, when I the portion 31 will engage therewith fixing the position of the plow the same as before it was raised. On themember 11 I provide a shoulder or stop 12 against which the lever 5 contacts when it is raised to its limit on the member 11 and the porti0n'31 of the latch 25 is in engagement with the notch 35.

When a greater or lesser depth of plowing is desi ed it is necessary to change the position of the member 11 on the quadrant 8, this I accomplish by operating the grip 24 to lift the latch 19, the hook 21 at the same time acting against the lug 22 and lifting the forward end of the member 11," simultaneously com ressing the spring 15 and releasing the 7 ortion 12 from engagement with a notch of the uadrant 8. As the member 11 is raised it lifts the latch 25. releasing the portion 35 from engageinentwith a notch of the mad rant 8. but retaining it in the n tch 35: a

' movement now oi" the lever 5 in either direction will move the. member 11 correspondinglv until the desired position for a new de th of plowing is reached. then the grip 24 is released and the tooth. 12 of the member 11 enga es with a notch of the quadrant 8 and is held in such engagement bythe expansion of the spring 15. at the same time the portion'31 of the latch 25 also engaging with the teeth of the quadrant. From this.

new position of the member 11 the lever can be again utilized to raise the plow. with the assurance that when the plow is lowered it will enetrate no dee er'than the de th de termined. the upward movement of the lever 5 stop ing as soon as the portion 31 of the latch 25 engages with the notch 35 and a notch of the uadrant 8. It will be noted that the member 11 and the quadrant 8 are of the same depth, consequentl the teeth of the uadrant 8 are covered by the member 11. the n tch 35 onlv permitting the portion 1 31 of the latch 25 to engagewith the teeth of the quadrant 8.

I ha e shown and described mv invention as applied to a plow. but it is plainlv evident that it may be employed in numerous other engagement therewith and adapted to limit the movement of the lever, and means on the lever to disengage said. member from the quadrant to change the position of said member by movement of the lever.
